That would be D as in "Delay " not D as in digital.
I have had the opportunity to drive to work for the last couple of days and have been listening to the radio as they discussed this issue. I used to wonder why television stations should be forced to switch to digital signals. Now I recognize that Congress has been holding them back from switching to digital signals exclusively. That leaves me with the question of why it is so important that everybody be able to receive a television signal.
I know I’m odd in the fact that I never watch television (since the middle of 2000), but I really don’t understand why television stations should be forced to serve people through analog. Some will argue that television is an important news source. I argue that the "news" that comes on television is somewhere between uninformative and misinformative most of the time. Some will argue that the entertainment is important. Though I find little television entertainment worth watching (yes, I still do have a vague idea of what’s offered), none of it is necessary and why should Congress be involved in mandating our entertainment options? (I can’t seem to find that section in my pocket Constitution.) Next thing you know, Uncle Sam will be giving away 5 free movie tickets per person per year – like they do in New Zealand (I may be wrong on the exact quantity).
Considering what I heard about how much cheaper it is for stations to broadcast in digital I would bet that, if left to themselves, the television broadcasters would figure out a way to offer the financial incentive necessary to get their customers to switch to digital. But that would be a free market and <sarcasm>we wouldn’t want to try that – free market’s aren’t stable.</sarcasm>
